I have gone through your query.
For your kind information steroid
nasal sprays rarely causes any side-effects because they are sprayed directly to the nose and very little of this medicine are absorbed into the body. Therefore, they are much less likely to cause side-effects in other parts of the body.
There for no need to worry but I personally advised to reduce the dose to a lower maintenance dose.
If you have any doubt, I will be available for your query.
Wish you good health.
